Disorder enhanced ferromagnetic polaron formation -- and the test case of Europium Oxide
Europium Oxide (EuO), a low carrier density local moment ferromagnet, shows a wide variety of transport behaviour depending on preparative conditions. Some samples have a moderate resistivity with a modest peak near $T_c$ while others show a huge peak in resistivity followed by insulating high temperature behaviour. These features have been known for decades and have been attributed to the presence of magnetic polarons in a disordered background. Actual attempts at a theory, however, reduce the…
